IMPORTANT SAFETY GUIDELINES
Safety of the operator and bystanders is one of the
main concerns in designing and developing a machine. However, every year many accidents occur
which could have been avoided by a few seconds of
thought and a more careful approach to handling
equipment. You, the operator, can avoid many
accidents by observing the following precautions
in this section. To avoid personal injury or death,
study the following precautions and insist those
working with you, or for you, follow them.
•
Avoid blank hammering.
•
DO NOT hammer in the same tool position for
over thirty (30) seconds.
•
DO NOT use the breaker to move material, pry
material or any other use that it is not designed
for.
•
DO NOT submerge the breaker under water
unless the breaker has been modified for underwater operation.
•
Replace any safety sign or instruction sign
that is not readable or is missing.
•
•
NEVER use alcoholic beverages or drugs
which can hinder alertness or coordination
while operating this equipment. Consult your
doctor about operating this machine while
taking prescription medications.
Prevent contaminiation from entering the
hydraulic hoses when mounting or dismounting
the breaker from the machine.
•
Maintain a clean hydraulic system.
•
Replace the filter element with a new one and
change hydraulic oil at the specified intervals.
•
Under no circumstances should young
children be allowed to work with this
equipment. Do not allow persons to
operate or assemble this unit until they
have read this manual and have developed a thorough understanding of the
safety precautions and of how it works.
Review the safety instructions with all users
annually.
•
This equipment is dangerous to children and
persons unfamiliar with its operation. The
operator should be a responsible, properly
trained and physically able person familiar
with the machine and trained in this equipment's operations.
•
Perform daily inspections.
4
Filter Element ------- Every 100 hours
Hydraulic Oil -------- Every 800 hours
•
Operate the breaker carefully. DO NOT hit the
boom of the machine with the breaker.
In addition to the design and configuration of this
implement, including Safety Signs and Safety Equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence
and proper training of personnel involved in the operation, transport, maintenance and storage of the
machine.
Think SAFETY! Work SAFELY!
2.3
SAFETY TRAINING
Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to
provide safe equipment can be wiped out by a single
careless act of an operator or bystander.
How To Install Safety Signs:
In addition to the design and configuration of equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence
and proper training of personnel involved in the operation, transport, maintenance and storage of this
equipment.
•
•
It has been said, "The best safety feature is an
informed, careful operator." We ask you to be that
kind of an operator. It is
the operator's responsibility to
read and understand ALL
Safety and Operating instructions
in the manual and to follow these. Accidents can be
avoided.
Working with unfamiliar equipment can lead to careless injuries. Read this manual, and the manual for
your machine, before assembly or operating, to acquaint yourself with the equipment. If this implement
is used by any person other than yourself, or is loaned
or rented, it is the machine owner's responsibility to
make certain that the operator, prior to operating:
a.
Reads and understands the operator's
manuals.
b.
Is instructed in safe and proper use.
Know your controls and how to stop machine quickly
in an emergency. Train all new personnel and review
instructions frequently with existing workers. Be certain only a properly trained and physically able person
will operate the machinery. A person who has not read
and understood all operating and safety instructions
is not qualified to operate the machine. An untrained
operator exposes himself and bystanders to possible
serious injury or death.
2.4
SAFETY SIGNS
1. Keep safety signs clean and legible at all times.
2. Replace safety signs that are missing or have
become illegible.
3. Safety signs are available from your authorized
dealer or from Gearmore.

Be sure that the installation area is clean
and dry.
Be sure temperature is above 50º F (10º C).
Determine exact position before you remove
the backing paper.
Remove the smallest portion of the split
backing paper.
Align the sign over the specified area and
carefully press the small portion with the
exposed sticky backing in place.
Slowly peel back the remaining paper and
carefully smooth the remaining portion of the
sign in place.
Small air pockets can be pierced with a pin and
smoothed out using the piece of sign backing
paper.
HYDRAULIC SAFETY
Make sure that all the components in the
hydraulic system are kept in good condition
and are clean.
Replace any worn, cut, abraded, flattened or
crimped hoses and metal lines.
Relieve pressure before working on
hydraulic system.
Do not attempt any makeshift repairs to the
hydraulic lines, fittings or hoses by using
tapes, clamps or cements. The hydraulic
system operates under extremely high
pressure. Such repairs will fail suddenly
and create a hazardous and unsafe
condition.
Wear proper hand and
eye protection when
searching for a high
pressure hydraulic leak.
Use a piece of wood or
cardboard as a backstop
instead of hands to isolate
and identify a leak.
If injured by a concentrated high pressure
stream of hydraulic fluid, seek medical
attention immediately. Serious infection or
toxic reaction can develop from hydraulic
fluid piercing the skin surface.
Before applying pressure to the system,
make sure all components are tight and
that lines, hoses and couplings are not
damaged.
When disconnecting hydraulic lines, shut off
hydraulic supply and relieve hydraulic
pressure.

OPERATION
5.1
INSTRUCTIONS FOR USING THE HYDRAULIC BREAKER
BEFORE STARTING THE BREAKER:
•
CHECK THE NITROGEN GAS PRESSURE
The nitrogen gas precharge is factory checked before you receive your breaker, but it is recommended the pressure be checked before using the breaker for the first time. Please refer to the relevant section of this manual
to understand how to check the gas pressure.
•
PRE-OPERATION INSPECTION AND WARM UP
Before operating any of our hydraulic breakers, be sure to perform these routine inspection procedures. Please
carry out the following inspection before use:
•
Check for any signs of visual damage to the breaker. Early detection of any problems can
prevent further potentially serious damage to the breaker or the machine.
•
Lubricate the tool and tool bushing. To ensure that no damage occurs, caused by seizing, to
the tool or tool bushing by greasing the working parts every 2 - 3 hours. Introduce grease,
via a grease gun, through the fitting located near the working end of the breaker.
BREAKER
LUBRICATION SCHEDULE
All Models
5-6 Shots of grease every 2 to 3 hours
(dependent on working conditions)
•
Check for tool and tool bushing wear. Replace the tool and/or bushings if there is wear or
damage to either part. Please refer to the section highlighting the maximum allowable
clearances between the tool and tool bushing (see Clearances Between Tool and Tool
Bushing).
•
Check all bolts for tightness. The necessary tightening torque settings can be found in the
service manual.
•
Inspect all welds for cracking and damage and repair as necessary.
•
All hoses must be checked for leaks. Change all hoses that have incurred damage that could
cause failure of hose during operation of the hydraulic breaker.
•
Check for any signs of damage to the tool retaining pin.
YOU MUST CHECK THE HYDRAULIC OIL REGULARLY TO PREVENT DAMAGE
TO THE BREAKER AND/OR THE HYDRAULIC SYSTEM ON THE MACHINE.
Check the hydraulic oil tank for level and the contamination and/or deterioration of the hydraulic oil. Change
and filter element at specified number of hours as given in the relevant section of this manual. For instructions
on how to change oil and filter element refer to the operators manual of the machine.
Warm up the hydraulic breaker and the backhoe or excavator in accordance with the machine instruction
manual. The warming up procedure is essential during cold weather operation.
8
5.2
INITIAL OPERATION OF HYDRAULIC BREAKERS
Operate the breaker in the upright position, with the engine at half throttle for approximately one hour.
During this period it is essential to inspect the breaker for loose bolts and any leaks. Check the attached hoses
and tubing for any leaks as well.
ATTENTION: The breaker should be working in the
upright position during the initial start up period.
5.3
OPERATING YOUR HYDRAULIC BREAKER
Hydraulic breakers are very simple to use and the following operating procedure outlines the best way to use
your breaker. To get the most from your breaker the operator should understand the following points:
•
Press the tip of the tool vertically against the object to be broken.
•
Apply a slight downward force on the breaker tool by raising the backhoe / excavator / skid
steer and start the breaker by pressing the foot pedal/control lever.
ATTENTION: Do not raise the machine too high as
the application of excessive force on the breaker will
cause jolting of the machine during operation.
•
5.4
As soon as the material is broken the operator must stop hammering (Release control pedal/
lever).
ATTENTION:
Continuation of blank hammering
will cause damage to the breaker and the machine
hydraulic system.
POINTS TO NOTE WHEN USING YOUR HYDRAULIC BREAKER
•
DO NOT USE THE CHISEL AS A PRY BAR
Excessive prying can cause premature bushing wear, tool and/or side bolt breakage.
•
DO NOT HAMMER CONTINUOUSLY IN THE SAME POSITION FOR MORE THAN
THIRTY (30) SECONDS
If the tool cannot break or penetrate into the material after hammering in the same position
for thirty seconds, change the working location. Hammering in the same position for a long
time will reduce the working efficiency, increase the hydraulic oil temperature, and
accelerate tool wear (mushrooming of tool point).
•
ALWAYS WORK BY BREAKING TO A FREE FACE
•
DO NOT ALLOW THE TOOL TO HIT THE BOOM
Use caution when tucking the hammer in tight to the boom for transportation.
9
5.4
5.5
POINTS TO NOTE WHEN USING YOUR HYDRAULIC BREAKER
(continued)
•
DO NOT DROP THE BREAKER RAPIDLY ON AN OBJECT
Remember that a breaker is heavier than an empty bucket and will move faster than
expected.
•
DO NOT USE THE BREAKER TO MOVE LARGE OBJECTS
Do not use the hammer bracket for purposes other than for what it was intended.
•
AVOID OPERATING THE BREAKER WITH CYLINDERS AT THE END OF STROKE
Continuous operation with the boom cylinders fully closed or extended may damage the
hydraulic cylinders.
•
DANGER: BEWARE OF FLYING PROJECTILES FROM THE BREAKER TOOL
Do not use the breaker in such a way as to cause rock, concrete, etc. to be thrown towards the
machine's cab. Do not operate the breaker without checking that all of the applicable safety
equipment/shielding on the machine is fitting and working correctly. FAILURE TO
COMPLY MAY RESULT IN INJURY OR DEATH.
•
DO NOT USE THE BREAKER AS A HOIST
Breakers are not designed to pick up other objects. Do not use it as a hoist. We can not be
held responsible for injuries or damage caused by misuse.
•
DO NOT OPERATE BREAKERS UNDER WATER
Do not allow parts, other than the breaker tool, to be submerged in water. Underwater
operation will damage the breaker and the machine's hydraulic system.
